HCl + NaHCO3 → NaCl + H2CO3

Acid of the stomach (gastric acid, HCl) is neutralized naturally by sodiumbicarbonate (NaHCO3) secreted by the pancreas when the chyme enters the smallintestines (duodenum). This reaction can be accomplished by ways other thanentrance into the small intestine in cases of heartburn and upset stomach by
means of pharmaceuticals such as Rolaids.

Hydrochloric acid is a solution of Hydrogen Chloride in water, that is a highly corrosive, strong mineral acid with many industrial uses. It is found naturally in gastric acid.
Historically called muriatic acid, and spirits of salt, hydrochloric acid was produced from vitiriol (sulfuric acid) and common salt. It first appeared during the Renaissance, and then it was used by chemists such as Glauber, Priestly and Davy in their scientific research.
If the stomach were not protected by mucus, hydrochloric acid (HCL) would burn the stomach lining. This powerful acid protects us from harmful bacteria—what we may ingest with foods is fried by this strong acid. HCL also helps keep the three pounds of bacteria found in the colon from moving up into the small intestine. If this happens, “bad” bacteria and yeast can establish a foothold in the intestine, resulting in less than optimum absorption of nutrients and inflamed intestines.
HCL is paramount in our digestive process. It begins the digestion of protein and stimulates the pancreas to produce digestive enzymes and bile. Without enough of these two substances, we cannot adequately digest or absorb carbohydrates, proteins, and fats. When we don’t digest foods well, there may be three results:
1) We don’t get the nutrition we need.
2) Badly digested foods continue through the digestive tract. Some of the larger molecules flow through the intestine into the bloodstream. (The inflamed intestines noted above make this easier.) These larger molecules are seen as invaders by the immune system and are attacked. The result is food allergies. It is estimated that 80 percent of patients with food allergies suffer from some degree of impaired hydrochloric acid secretion in the stomach.
3) Foods linger for much longer than they should in the digestive system, resulting in an overgrowth of unfriendly bacteria in the small intestine and colon. When these bad bacteria begin to outnumber the good bacteria, a condition known as dysbiosis exists. According to Elizabeth Lipski, M.S., C.C.N., in her book, Digestive Wellness, dysbiosis may result in such diverse conditions as arthritis, autoimmune disease, vitamin B12 deficiency, chronic fatigue syndrome, eczema, food allergies and food sensitivities, inflammatory bowel disease, and irritable bowel syndrome.

NaHCO3 (sodium bicarbinate) is used to reduce stomach acid, it is used as an heartburn to treat indigestion and heartburn it mostly gives you temporary relief. Sodium Bicarbonate is an active ingredient in things like baking soda and other thingslike all kinds of antacid.it neutralizes any kind of gastric acid in the body and blocks gastric enzymes that have an optima range of pH. It has been proven that a small dose of sodium bicarbonate can be used as a supplement for athletes to maintain their endurance and their fatigue.

SodiumChloride is one of the compounds in gastric acid,it is known as a salt, common salt, or table salt, it is an inorganic bond. It is most responsible for the salinity of the ocean and for the extracellular fluid in most multicellular orgasms, it is an important ingredient for edible salt, and it is mostly used as a food preservative and a condiment. Each ion in SodiumChloride is surrounded by six ions of the opposite charge. these surrounded ions are located at the vertices of a regular octahedron.

Carbonic acid is an inorganic compound, it's also a name sometimes given to solutions of carbon dioxide in water, because such solutions contain small amounts of H2CO3. Carbonic acid is intermediate step in the transport of CO2 out of the body via respiratory gas exchange. It is a irrespirable gas and can be reduced to a liquid or a solid due to high pressure, it can be produced in the fermentation of liquors. It is formed in the explosion of fire damp in minds, thats why it is called after damp and also known as choke damp.

HCl + NaHCO3 → NaCl + H2CO3 is a very important chemical reaction because it is a main ingredient in baking soda which can reduce stomach acid. It is also used in other stomach acid controlling things like pepto bismo and tums, without it, the stomach acid in our body would start bubbling up until it starts to get into the throat. the equation can easily form from drinking alkaline water. Our body already contains HCl and alkaline water has most of the ingredients such as NaHCO3, and NaCl and H2O and CO2 which can bond to form H2CO3.In conclusion we think that chemical reactions can be very important because nearly all of them can help with the body and make sure that it is working perfectly. Mostly because the compounds and elements bond to form kinds of medicine. Like all these kinds of antacids, others can be deadly but it counts on how it is formed. there are all kinds of chemical reactions in the world all made from different elements. this entire page explains how one chemical reaction can help you with stomach acid, and that is why chemical reactions are important in everyday life.
